Created structure of the application has such advantages as compactness and the ability to be expanded through the addition of new data sources, wich can increase the accuracy of the analysis.
The paper reviews the problem of age and gender recognition methods for video data using modern deep convolutional neural networks. We present the comparative analysis of classifier fusion algorithms to aggregate decisions for individual frames. We implemented the video-based recognition system with several aggregation methods to improve the age and gender identification accuracy. The experimental comparison of the proposed approach with traditional simple voting using IJB-A, Indian Movies, and Kinect datasets is provided. It is demonstrated that the most accurate decisions are obtained using the geometric mean and mathematical expectation of the outputs at softmax layers of the convolutional neural networks for gender recognition and age prediction, respectively.
In the last few years there has been a growing interest in route building oriented mobile applications with the following features of navigation and sending timely notifications about arrival. Despite the large body of existing knowledge on navigational services, there has been an important issue relative to positioning accuracy. The paper discusses a possible solution to comparison problem, which is linked to the determination of the closeness to destination metro station through finding a difference between user’s current coordinates and fixed-point coordinates. With this end in view, fuzzy logic approach is used to develop Routes Recommender System (RRS) that utilizes linguistic variables to express the vague and uncertain term ‘closeness to…’. The paper provides detailed explanation of each variable considered in the fuzzy inference system (FIS), set of fuzzy rules in line with graphical representation of system’s output. Based on Mamdani model, we propose a set of test cases to check maintainability of the model and provide a description about received results. At a later time, an Android-based mobile application aimed at public transport route building will be developed whose notification system will be based on our model`s implementation presented. It should be emphasized that the paper examines potentials of the modeling approach based on interval type-2 fuzzy sets (IT2FS) that attract much attention these days in various research studies and conventional Mamdani fuzzy inference system (MFIS) as applied to real and rather topical problem. The significance of developing such models may be of a high demand for appropriate representation of factors that are inherently vague and uncertain. Hence, this study may also contribute to future research on similar topics.
In this article, the effectiveness of content services is formalized on the basis of an analysis of the regulatory legal acts regulating the relationship in the market for consuming content services. The use of cloud computing for the widespread introduction of services to assess the consumer quality of content services is considered. The article describes the security aspects and the possibility of implementing security requirements for mobile applications and discusses the proposed circuit-technical options for implementing the principles of building information-safe mobile applications that are reducible to the typical info-communication technological interaction.
Because of rapid mobile technologies expansion, there is a gap between the complexity of mobile applications and the complexity of employed testing techniques. This paper is aimed at reducing the gap from the theoretical point of view. The paper comprises an analysis of mobile applications testing processes, mobile applications testing metrics, along with the full test coverage criterion. It also contains an integral criterion of the testing processes optimization which is based on the idea of summing the corresponding sub-processes times. The presented criterion leads to an assumption of the tests generation approach efficiency. Therefore a partial criterion of the tests generation process is proposed. The mathematical model of this partial criterion is based on the properties of different algebraic expressions. The numerical results section includes processes comparison and some estimates.

Because of rapid mobile technologies expansion, there is a gap between the complexity of mobile applications and the complexity of employed testing techniques. This paper is aimed at reducing the gap from the practical point of view. Tests generation techniques are widely spread, but none of them are optimized for mobile applications. This paper proposes an analytical model of tests generation process, which is based on prototypes and takes mobile specificity into consideration. Along with this an analysis of existing tests generation approaches has beenmade. The flowchart of the proposed model has been submitted with the model. The efficiency of the model has been described in the numerical results section.
